16 Electromechanical Level Control Class 9036, 9037, and 9038 Introduction Square D Level Control Products 9036DG2 Square D brand offers a wide range of electromechanical level control products. The current offering is described below: Class 9036, Open Tank Class 9037, Closed Tank Class 9038, Mechanical Alternators NOTE: The Class 9039 Duplex Controller (electrical alternator) is also available but is not covered in this catalog. Class 9036 Open Tank Type D and G 9036GG The Class 9036 Type D and G float switches are lever operated and designed for open tank applications. These switches are floor mounted, or they can be pedestal mounted using mounting plate 9049UMS1. They are available in NEMA Type 1, NEMA Type 4, or NEMA Type 7 and 9 enclosures. Type G The Class 9036 Type G30 pedestal-style sump pump switch is designed for liquid level control with electric-motor operated pumps either directly or through a magnetic starter. It can also be used to activate alarms in liquid level control systems. The upward or downward movement of the lever arm of the float switch controls the On and Off positions corresponding to the water levels changes required to turn the pump or alarm on and off. NOTE: The rod for this device is in. long. It cannot be lengthened. 9036G 9049A A Schneider Electric All Rights Reserved 05/2008

17 Introduction Electromechanical Level Control Class 9036, 9037, and 9038 Class 9037 Closed Tank Type E The Class 9037 Type E switches are flange mounted. loat movement is transmitted through a quad ring seal. Each switch consists of a basic switch, float rod, and float. The switch can be configured in the field for contacts that open on liquid rise or close on liquid rise. These switches are used for top mounted or side mounted, closed tank applications. 9037E 9037H Type H The Class 9037 Type H switches are attached to the tank by means of a 2-1/2 in. bushing. An external pointer indicates the float position within the tank when the unit is mounted. Switches come complete with stainless steel float and rod. A nitrile rubber seal, such as a Buna-N quad ring seal, is used between the float rod and the sealing connector. Normal application is at atmospheric pressure. Where higher pressures are encountered, the available Viton seal allows the switch to withstand tank pressures up to 50 psi at ambient temperatures up to 220. Occasional replacement of the quad ring seal may be necessary. Class 9038 Mechanical Alternators Type A (Open Tank) 9038AG1 9038CG The Class 9038 Type A Open Tank level switch is a mechanical alternator designed to provide motor alternation in the operation of two motors. Type C (Closed Tank, Bushing Mounted) The Class 9038 Type C Closed Tank level switches are bushing mounted. loat movement is transmitted through a quad ring seal. Each switch consists of a basic switch, rod, and float. Type C switches are attached to the tank by means of a 2-1/2 in. bushing. An external pointer indicates the float position within the tank when the unit is mounted. Switches come complete with bushing, stainless steel float, and rod. Occasional replacement of the quad ring may be necessary. Type D (Closed Tank, lange Mounted, Top) Type D mechanical alternators are designed for applications where flange mounting is to be made at the top of a closed tank. 9038DG 9049ER5 9049E1 05/ Schneider Electric All Rights Reserved 17

18 Electromechanical Level Control Selecting a loat Switch Introduction Selecting a loat Switch 9036DG2 Standard float switches have two contacts that close when the liquid rises above the designated level. This contact configuration is used for tank emptying applications. loat switches are also available with reverse (orm R) and double throw (orm H) contacts. orm R switches, used for tank filling applications, have two contacts that open when the liquid rises above the designated level. orm H switches, which can be used for both applications, have one normally open (N.O.) and one normally closed (N.C.) contact. To select the proper Square D float switch, determine the following: Type and shape of tank (open, closed, sump, etc.) Enclosure requirements NEMA Type 1: or general purpose applications intended for indoor use. NEMA Type 4:or watertight and dusttight applications for either indoor or outdoor use. NEMA Type 7 and 9: or explosion proof applications. Suitable for Class I, Division 1 and 2, Groups C and D and Class II, Division 1 and 2, Groups E,, and G hazardous locations. 9036GG2 Total level change required Mounting requirements (such flange mounting or screw-in bushing) Horsepower, phase, and voltage requirements loat material Stainless steel (SS) Plastic (available on 9036G30 and as a orm for use with diesel fuel) Rod material Brass Stainless steel (SS) Aluminum (Al) In direct motor control applications, float switch ratings must be greater than or equal to the pump motor ratings. NOTE: Consult your local Square D field office when using float switches in liquids with a specific gravity different than water (1.0). The following information must be included for each float switch ordered: Basic switch: Class and Type Accessory kits: Class and Type Selecting loats and Rods Class 9036 and Class 9038 Type A float switches are actuated with the Class 9049 Type A line of accessories. Select the float and rod material according to the corrosiveness of the liquid used in the application. Two types of float kits are offered: Tapped-at-top float (Class 9049 Type A6, A6S, and A6A) Center-hole float (Class 9049 Type A6C, A6CS, and A6CA) The tapped-at-top float is for applications requiring short lengths of tubing and small liquid level changes. The maximum tubing length is 12 ft (3.66 m). Adequate space must be available to allow for ceiling clearance when the level changes. The float must be buoyant enough to lift the tubing, stop collars, and switch lever. The rod has two stops, one above and one below the switch lever. The position of the stops determines the amount of water level change Schneider Electric All Rights Reserved 05/2008

19 Introduction Electromechanical Level Control Electrical Ratings The center-hole float is used in applications requiring long lengths of tubing and large liquid level changes. A compensating spring, used for longer lengths of tubing, supports the weight of the tubing and stops. When a compensating spring is used, the float must be buoyant enough to lift up the switch lever and heavy enough to trip the switch lever down. The rod has four stops. The position of the stops on the rod above and below the float determines the amount of water level change. Temperature Ratings Table 1: Temperature Limitations or All loat Switches Ambient Min.

30 Electromechanical Level Control Class 9038 Type A Mechanical Alternators Specifications and Class 9038 Class 9038 mechanical alternators provide a simple, positive means of mechanically alternating two pumps or motors. These alternators are used on devices that are installed in a duplex system with a common tank. There are three types of Class 9038 mechanical alternators: Type A (open tank and sump) Type C (with bushing) Type D (flange mounted, vertical) When liquid level rises to the first level, one pump turns on. Both pumps automatically turn on when a peak condition occurs and the liquid level continues to rise. If orm N5 or N25 is present, and the water level continues to rise, a high water alarm is activated. Mechanical alternators can be ordered with a manual transfer selector switch (orm N3), which allows the operator to select which pump cuts in first. The second pump only operates under peak demand conditions or if the first pump fails. When the switch is disengaged, the alternator reverts to normal operation. Another option (orm N4) allows the alternator to be used as a two-level non-alternating unit. Class 9038 Type A, Open and Sump Tank Mechanical Alternators 9038AG1 Table 14 contains ordering information for Class 9038 Type A mechanical alternators, including factory installed modifications. Order float accessories separately. Consult your local Square D field office when using Class 9038 alternators in liquids with a different specific gravity than water (1.0). When ordering a factory modification, add the orm number to the end of the mechanical alternator catalog number. or example, to select a 9038AG1 alternator with reverse action, order 9038AG1R.
